This guide explains how oncology clinics in Korea work, what services are available, how foreigners can access care, and what to expect during treatment.

What Is an Oncology Clinic?

Basic Overview

An oncology clinic is a specialized medical facility focused on the prevention, diagnosis, and treatment of cancer. Oncologists are doctors trained in managing different types of cancer using medical, surgical, and radiation-based approaches. In Korea, oncology services are usually part of large hospitals or university medical centers rather than small standalone clinics.

Who Typically Uses Oncology Services

Oncology clinics treat patients with: suspected or confirmed cancer, blood-related cancers (leukemia, lymphoma), solid tumors (lung, breast, stomach, liver, colon, etc.), metastatic or advanced-stage cancers, patients requiring long-term cancer management.

Common Oncology Services

Typical services include: cancer screening and early detection, diagnostic imaging (CT, MRI, PET scans), biopsy and pathology testing, chemotherapy, radiation therapy, immunotherapy and targeted therapy, surgical oncology, palliative care and pain management.
